Yawning and cortisol levels in multiple sclerosis: potential new diagnostic tool

Publication date: Available online 2 May 2018 Source:Multiple Sclerosis and Related Disorders Author(s): Simon B N Thompson, Alister Coleman, Nicola Williams Yawning is a significant behavioural response and, together with cortisol, is potentially a new diagnostic marker of neurological diseases. Evidence of an association between yawning and cortisol was found which supports the Thompson Cortisol Hypothesis and thermoregulation hypotheses, indication that brain cooling occurs when yawning. 117 volunteers aged 18-69 years were randomly allocated to experimentally controlled conditions to provoke yawning. Thirty-three had been diagnosed with multiple sclerosis. Saliva cortisol samples were collected before and after yawning or after stimuli presentation in the absence of yawning. Hospital Anxiety and Depression Scale, General Health Questionnaire, demographic and health details were collected. Comparisons were made of yawners and non-yawners, healthy volunteers and MS participants. Exclusion criteria: chronic fatigue, diabetes, fibromyalgia, heart condition, high blood pressure, hormone replacement therapy, stroke. Yawners had significant differences between saliva cortisol sample 1 and 2 among healthy participants (p<.007) and MS participants (p<.003). There was significant difference between the healthy versus MS non-yawners (P<.042) but not between yawners (p<.862). These results support the Thompson Cortisol Hypothesis suggesting that cortisol levels are eleva...

In conclusion, our results indicate that LRP1 promotes the dedifferentiation of PASMC from a contractile to a synthetic phenotype thus suggesting its contribution to vascular remodeling in PH.

Recently, we have shown that n-butylidenephthalide (BP) improves human adipose-derived stem cell (hADSC) engraftment via attenuated reactive oxygen species (ROS) production. This prompted us to investigate whether remote transplantation of BP-pretreated hADSCs confers attenuated LVH at an est...

Publication date: Available online 21 March 2019Source: MitochondrionAuthor(s): Hamza El Hadi, Roberto Vettor, Marco RossatoAbstractCardiovascular disease is the leading cause of diabetes-related morbidity and mortality. It is widely accepted that heart failure risk is increased in diabetic patients even after adjusting for coronary artery disease and hypertension. Mitochondria are the center of fatty acid (FA) and glucose metabolism and thus are likely to be impacted by impaired metabolism associated with diabetes. Although the cause of this increased heart failure risk is multifactorial, increasing evidence points toward...
